Theplents ere set out in rows, and the rote'ctors are placed over the lents. A ine wireV passin through the s ot 'i and under the, row, V sind ai lever m 1e pivoted to the upright l, end the Wirec is connected to seid :leven-asshown at n. There is an upright l for each row, endthese uprights are provided with racks `c 4to hold the levers m in adjusted positions. By this means all the tops orcovers of a row of protectors are opened vand closedsimultaneously by the movement of the lever m.
